Subject: [Qemu-devel] [PATCH for-2.0 0/2] mirror: fix rate-limiting
Date: Fri, 21 Mar 2014 13:55:17 +0100 [thread overview]
Message-ID: <1395406519-21410-1-git-send-email-stefanha@redhat.com> (raw)
Rate-limiting is broken for drive-mirror because the calculations are performed
using an inaccurate sector count and aio completion is waking up the sleeping
coroutine early. These patches from Paolo and me fix the issue.
Paolo Bonzini (1):
mirror: fix throttling delay calculation
Stefan Hajnoczi (1):
mirror: fix early wake from sleep due to aio
